Get the standard ports and run all the scripts and checks on them:
nmap -n -v -sT -sV -A <IP or FQDN> -oN nmap | tee "nmap_$(date '+%Y-%m-%d_%H-%M-%S').txt"
Get a full TCP scan:
nmap -n -v -sT -sV -p- -Pn -A -T5 -sC <IP or FQDN> -oN nmap | tee "nmap_$(date '+%Y-%m-%d_%H-%M-%S').txt"
Using a file with IP list:
nmap -n -v -sT -sV -p- -Pn -A -T4 -sC -iL <filename.txt> -oN nmap | tee "nmap_$(date '+%Y-%m-%d_%H-%M-%S').txt"
Get a SYN scan:
<aside> ℹ️
The SYN scan sends a SYN packet (which is the first part of the TCP handshake sequence) to a port, and analyzes the response to determine whether the port is open, closed, or filtered.

nmap -v -A -O -sV -p- -T4 -Pn -sS -sC <IP or FQDN> -oN nmap | tee "nmap_$(date '+%Y-%m-%d_%H-%M-%S').txt"
Get Stealth Scan:
nmap -v -A -O -p- -T4 -Pn -sS -sC <IP or FQDN> -oN nmap --scan-delay 3s --max-parallelism 1 -Pn | tee "nmap_$(date '+%Y-%m-%d_%H-%M-%S').txt"
